Short CV

Anabela A. Valente studied chemical engineering at the Universidade Nova de Lisboa (Portugal) and received her doctorate in chemical engineering/catalysis from the same university. After a post-doctoral period at the University of Aveiro (UA, Portugal), in the field of Materials Engineering, she became assistant researcher at CICECO-Aveiro Institute of Materials (UA, 2003). Since 2015, she has held the position of principal researcher at the same institution. Her research is related to applied homogeneous/heterogeneous catalysis and materials science. She is responsible for a team interested in the chemical valorisation of biomass-derived compounds via catalytic routes. She trained scientists at several levels (MSc, PhD, post-doc) in the development of their scientific careers (some integrated the industry in the field in which they were trained by AAV). She has collaborated with members of different national (e.g., Lisbon, Algarve) and foreign (e.g. Spain, UK, Germany, Ukraine, Poland) universities in the development of multidisciplinary research works, and some reference players from the industry (Merck KGaA, Bosch). She has been involved in several scientific projects with competitive funding. She is co-author of ca. 235 papers in peer-reviewed scientific journals and over 290 communications at national/international conferences; h-index = 50 (Scopus), over 7000 citations (without self-citations) and ca. 82 % of her scientific articles are in the top 25% journals by CiteScore (Scopus). She was elected twice as member of the Scientific Council of the UA (2009; 2013). In 2019-2024, she was co-director of the Department of Chemistry (UA). AAV was board member (for Portugal) of the Federation of European Zeolite Associations, FEZA, in 2020-2024. AAV is Chemistry Europe Fellow (Fellows Class 2020/2021). She is presently Coordinator of the Central Laboratory of Analysis, an executive unit of the University of Aveiro.

Specific scientific interests: applied catalysis, oxidation catalysis, acid-base catalysis, de/hydrogenation, chemical valorisation of biomass, synthesis and characterisation of materials.

Scientific Interests

- Synthesis and characterisation of heterogeneous catalysts.
- Homogeneous and heterogeneous catalysis: oxidation and acid-base reactions.
- Liquid-phase catalytic processing of biomass-derived compounds: oxidation of monoterpenes, conversion of saccharides into furan derivatives and bioesters, isomerization of sugars.
